Mod doesn`t initialize in minecraft

[TheASTRO]

Hello.  After I`ve imported a mod source from github to my workspace, I discovered, that minecraft does not see this mod. Only its 3 default mods. What may course this problem?

How did this "import" take place? How is your workspace set up?

Cloned git from GitHub to my "forgemods" folder. Executed 2 commands: gradlew setupDecompWorkspace and gradlew eclipse. Then switched workspace to "forgemods" folder and then imported its content. Configured  Run Client and Run Server and started the game. Forge doesn`t see this mod.

Is the mod source marked as a source folder? 

Yep.

Well, I`ve just compiled mod and placed it in mods folder. It worked. So why doesn`t it work without compiling?
